This has yet again prompted questions about the difference between legality and morality of online activism.

Dai Davis, an engineer and solicitor, thinks much of the debate around the legality of hacktivism is confused by the ambiguous nature of UK law. “Under the idiotic strict legal definition of what is legally allowed – like ‘computer misuse’ – then most things Anonymous do is unlawful.

"But so would using your hotel key card in the wrong door."

Morality does play a part in determining what is and isn't lawful. “Lawfulness is a morality judgement and it’s a relative term."

And what of the future of the law around hacktivism? “Votes aren’t won or lost because of hacktivism and not all hacktivism is bad,” Davis says.

While the law remains ambiguous, hackers continue to tread the fine line of legality and morality - but with their selection of unanimously reviled targets like ISIS, public support for online activists may remain.
